Have you also been noticing your hot water supply diminishing? The white particles are probably from the dip tube in your water heater deteriorating and flushing out through the water pipes.

: In our master bath the aerators on the faucets fill up with white sediment that evenually stops the water flow. I clean them and within minutes the water flow slows and within days stops and must be cleaned again.: What is the cause of this continual problem? No other faucets in the house seem to be affected.
